Cocaine- and amphetamine-regulated transcript (CART) peptide (CART-(55-102)) is involved in the suppression of food intake. We now report that CART-(55-102) is involved in anxiety in rodents. Intracerebroventricularly administered CART-(55-102) as well as intraperitoneal administration of N-methyl-beta-carboline-3-carboxamide (FG-7142), a selective(More)
We investigated the effects of a novel melanocortin-4 (MC4) receptor antagonist,1-[(S)-2-(4-fluorophenyl)-2-(4-isopropylpiperadin-1-yl)ethyl]-4-[4-(2-methoxynaphthalen-1-yl)butyl]piperazine (MCL0129) on anxiety and depression in various rodent models. MCL0129 inhibited [(125)I][Nle(4)-D-Phe(7)]-alpha-melanocyte-stimulating hormone (alpha-MSH) binding to MC4(More)
Muricidal behavior of the rat was induced by repeated s.c. administration of cadmium (Cd) for 15 weeks. The number of muricidal rats increased with increase in the duration of Cd administration in association with greater accumulation of Cd in the olfactory bulb than in any other region of the brain. The whole brain norepinephrine (NE) level of the rats(More)
Atypical antipsychotic properties of 4-(4-fluorobenzylidene)-1-[2-[5-(4-fluorophenyl)-1H-pyrazol-4-yl]ethyl] piperidine (NRA0161) were investigated by in vitro receptor affinities, in vivo receptor occupancies and findings were compared with those of risperidone and haloperidol in rodent behavioral studies. In in vitro receptor binding studies, NRA0161 has(More)
In vitro and in vivo pharmacological properties of 5-[2-[4-(6-fluoro-1H-indole-3-yl)piperidin-1-yl]ethyl]-4-(4-fluorophenyl)thiazole-2-carboxylic acid amide (NRA0562), a novel atypical antipsychotic, were investigated. NRA0562 showed high affinities for human cloned dopamine D(1), D(2), D(3) and D(4) receptors with Ki values of 7.09, 2.49, 3.48 and 1.79 nM.(More)
